qhia:
Polyvinyl chloride resin, feem ntau hu ua PVC resin, yog ib qho polymer compound polymerized los ntawm vinyl chloride monomer (VCM). Vim nws cov khoom siv ntau yam thiab muaj zog, PVC resin tau siv dav hauv ntau yam lag luam, suav nrog kev kho mob. Hauv qhov blog no, peb yuav tshawb nrhiav qhov tseem ceeb ntawm PVC resin ua cov khoom siv kho mob thiab nkag siab txog cov yam ntxwv xws li txheej txheem polymerization, cov xwm txheej ntawm cov tshuaj tiv thaiv, cov tshuaj muaj pes tsawg leeg thiab cov khoom ntxiv cuam tshuam rau nws qhov kev ua tau zoo.

Polyvinyl chloride resin: ib qho ze dua
PVC resin yog tsim los ntawm polymerizing vinyl chloride monomer, txheej txheem uas tsim cov saw ntev ntawm cov qauv CH2-CHCl. Lub degree ntawm polymerization, feem ntau yog 590 mus rau 1500, pab ua kom lub zog thiab durability ntawm cov khoom.

Cov ntawv thov hauv kev kho mob
PVC cob yog siv dav hauv kev lag luam kho mob vim nws cov khoom zoo heev. Nws yog feem ntau siv los tsim cov khoom siv kho mob xws li cov hlab ntsha hauv cov hlab ntsha, cov hnab ntshav, catheters thiab hnab looj tes phais. PVC resin yooj yooj yim, meej, thiab tshuaj tiv thaiv ua rau nws zoo tagnrho rau kev siv kho mob.

Cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm PVC cob
Kev ua haujlwm ntawm PVC resin yuav txawv nyob ntawm ntau yam. Cov txheej txheem polymerization ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov hnyav molecular thiab qib ntawm polymerization. Cov kev mob tshwm sim, xws li qhov kub thiab txias, kuj cuam tshuam rau cov khoom ntawm cov khoom kawg. Tsis tas li ntawd, qhov muaj pes tsawg leeg ntawm cov tshuaj reactants thiab ntxiv cov tshuaj ntxiv tuaj yeem hloov kho cov khoom ntawm cov resin kom tau raws li cov kev xav tau tshwj xeeb.

Additives nyob rau hauv PVC cob
Additives feem ntau ntxiv rau PVC resin los txhim kho cov khoom tshwj xeeb. Piv txwv li, plasticizers tuaj yeem ua kom yooj yim, ua cov ntaub ntawv tsim nyog rau cov ntawv thov uas yuav tsum tau txav thiab khoov. Ntxiv cov stabilizers tuaj yeem txhim kho cov cua sov thiab lub teeb ua haujlwm ntawm cov resin thiab ua kom nws lub neej kev pab. Lwm cov additives muaj xws li cuam tshuam kev hloov pauv, lubricants thiab fillers, tag nrho cov uas pab txhim kho kev ua tau zoo thiab kev siv tau.

nyob rau hauv xaus:
Polyvinyl chloride resin, lossis PVC resin, tseem yog ib qho tseem ceeb hauv kev lag luam kho mob. Nws versatility, lub zog thiab tshuaj tiv thaiv ua rau nws cov khoom ntawm kev xaiv rau cov khoom siv kho mob. Nkag siab txog kev cuam tshuam ntawm cov txheej txheem xws li cov txheej txheem polymerization, cov xwm txheej cov tshuaj tiv thaiv, cov tshuaj muaj pes tsawg leeg thiab cov khoom ntxiv yog qhov tseem ceeb rau kev tsim cov PVC resins nrog cov khoom xav tau. Raws li kev siv thev naus laus zis, kev txhim kho ntxiv hauv PVC resin yuav ua rau lub neej yav tom ntej ntawm kev kho mob tshiab, thaum kawg tau txais txiaj ntsig zoo rau cov neeg mob thiab cov kws kho mob.
